The CW Network has handed out a full-season order for the new series Ringer, which airs Tuesday nights at 9 PM ET.

The show premiered to solid ratings when it debuted on September 13, although the numbers began to slide in the weeks that followed. However, last night's Episode 1.05: A New Kind of Bitch, saw a 33% ratings increase in the ever-important 18-49 demographic, and a 17% increase in total viewers, up to 1.7 million.

Sarah Michelle Gellar stars in Ringer as Bridget Kelly, a woman who runs from her troubles and assumes the life of her wealthy twin sister. Ioan Gruffudd, Nestor Carbonell, Mike Colter, and Tara Summers also star in Ringer.

Ringer is the first series CW has given a full-season order to this year. The network canceled H8R last week, and it still isn't clear if Hart of Dixie and The Secret Circle will receive back-nine orders.
